Overview

General Description

From Boulenger (1909)  p. 118-119.

Depth of body 4 to 4½  times in total length, length of head 4 to 4 1/3 times. Upper profile of head descending in a strong curve; snout much prolonged, tubiform, strongly compressed, curved downwards, its length 1 2/3  to 2 times postocular part of head, and 4 to 5 times its least depth, which nearly equals diameter of eye; latter 2/3 to 3/4 interorbital width; lower jaw with a compressed dermal appendage about as long as the eye; teeth conical, 3 in upper jaw, 4 in lower. Dorsal 26-30, originating above 6th to 8th ray of anal, its length 1½ to 1 4/5 times in its distance from head. Anal 29-34, nearer base of caudal than base of ventral. Pectoral obtusely pointed, 3/5 to 2/3 length of head, ventral 1/3 to 2/5; pectoral extending beyond base of ventral. Caudal densely scaled, with pointed lobes. Caudal peduncle 3½ times as long as deep, 2/3 to 3/4 length of head. 70-80 scales in lateral line, 12-18 / 19-21 in transverse series on body, 14-15 / 12-15 in transverse series between dorsal and anal, 12 round caudal peduncle. Brownish above; a rather indistinct dark, light edged vertical band between origin of dorsal and anal.

Total length 360 millim.
